What is an ATS Resume Checker?

An ATS resume checker is a tool that scans your resume the same way employers’ Applicant Tracking Systems do. Over 98% of Fortune 500 companies use ATS software to filter resumes before human recruiters see them. Our free ATS resume checker identifies formatting issues, missing keywords, and compatibility problems that could cause your resume to be rejected automatically.

The ATS resume scanner evaluates critical factors including file format compatibility, keyword density, section organization, contact information placement, and formatting complexity. By testing your resume with our tool before submitting applications, you can fix issues that would otherwise result in automatic rejection.

How ATS Systems Work

Applicant Tracking Systems (ATS) are software applications that help companies manage the hiring process. When you submit a resume online, it typically goes through an ATS before reaching a human recruiter. Here’s the process:

• Step 1: Parsing – ATS extracts information from your resume including contact details, work experience, education, skills, and keywords
• Step 2: Categorization – The system organizes information into standardized fields in its database
• Step 3: Ranking – ATS scores and ranks candidates based on keyword matches with the job description
• Step 4: Filtering – Only top-scoring resumes (typically 25% or less) are forwarded to human recruiters
• Step 5: Searchability – Recruiters search the database using specific keywords to find qualified candidates

Popular ATS platforms include Taleo (Oracle), Workday, Greenhouse, Lever, iCIMS, and BambooHR. Our ATS checker tests compatibility with all major systems.

Common ATS Resume Mistakes (and How to Fix Them)

1. Complex Formatting: Tables, text boxes, headers/footers confuse ATS parsers. Fix: Use simple single-column layout with clear section headings.

2. Unusual Fonts: Decorative or script fonts aren’t ATS-readable. Fix: Use standard fonts like Arial, Calibri, Georgia, or Times New Roman at 10-12pt.

3. Images and Graphics: ATS cannot read images, logos, or charts. Fix: Remove all graphics; use text-only formatting.

4. Creative Section Headings: “My Professional Journey” instead of “Work Experience” confuses ATS. Fix: Use standard headings like “Work Experience,” “Education,” “Skills,” “Summary.”

5. Missing Keywords: Not matching job description keywords results in low ranking. Fix: Include exact keywords and phrases from target job postings.

6. Abbreviations Only: Writing “SEO” without spelling out “Search Engine Optimization” reduces keyword matches. Fix: Spell out acronyms on first use, then use abbreviation.

7. Contact Info in Header: Some ATS can’t read header/footer content. Fix: Place contact information in the main body at the top.

8. Inconsistent Dates: Mixed date formats (MM/YYYY and Month Year) confuse parsers. Fix: Use consistent format throughout (e.g., “January 2020 – Present”).

What Makes a Resume ATS-Friendly?

Standard Section Headings: Use common headings that ATS systems recognize:

• Contact Information (or Professional Profile)
• Professional Summary (or Summary/Objective)
• Work Experience (or Professional Experience/Employment History)
• Education
• Skills (or Technical Skills/Core Competencies)
• Certifications (optional)
• Additional Information (optional)

Simple Formatting: Avoid these ATS-unfriendly elements:

• Tables and text boxes
• Multiple columns (except for skills/certifications sections)
• Headers and footers (place all content in main body)
• Images, logos, photos, charts, or graphics
• Special characters and symbols (★, →, •)
• Fancy fonts or multiple font types
• Colored text or backgrounds
• Hyperlinks (spell out URLs instead)

Keyword Rich Content: Include relevant industry keywords, skills, and job titles from the job description. Our ATS checker identifies missing keywords to help you optimize.

Proper File Format: DOCX is generally safest for ATS compatibility. PDF works with modern ATS but can cause issues with older systems. Avoid image-based PDFs.

Understanding Your ATS Score

90-100 (Excellent): Your resume is highly ATS-compatible with proper formatting, strong keyword usage, and clear section organization. You have an excellent chance of passing automated screening and reaching human recruiters. Submit with confidence!

75-89 (Good): Your resume is generally ATS-friendly with minor improvements needed. Address the flagged issues (usually keyword density or minor formatting problems) to increase your interview chances by 15-25%.

60-74 (Fair): Your resume has moderate ATS compatibility issues. Several formatting problems or keyword gaps need attention before applying. Making recommended changes typically improves pass rate by 40-60%.

Below 60 (Poor): Your resume has significant ATS compatibility issues that will likely result in automatic rejection. Major revisions required including formatting overhaul and keyword optimization. Following our recommendations can improve pass rate by 80%+.
